  • Pass associative arrays in call_user_func_array(...)

    - by Matt
    Hey all, I'm building a templating system and I'm running in to an issue with calling functions on the fly. When I try the following: $args = array( 4, 'test' => 'hello', 'hi' ); You know.. some numerical elements some associative elements, call_user_func_array($function, $args); converts the array to something like this: $args = array( 4, 'hello', 'hi' ); Is there any way around this other than passing an array like this: $args = array( 4, array('test' => 'hello'), 'hi' ); Thanks! Matt

  • How do you get notified of your repos' updates?

    - by furtelwart
    I'm working on several repositories at work and would like to be informed, if anything changes in the SVN repositories. I made a small BAT script (yes, BAT is usefull sometimes) that keeps executing an svn log -r BASE:HEAD on my working copy. It shows all submit comments and revision dates. It works really well but it's not comfortable for different repositories. How do you keep track of changes in your repositories? Do you use a small program you made for yourself? Do you use software someone else made? I'm interested in every approach to this problem. I would like to get notifications and several more information about the commit. The IDE integrated functions are good, but work only if I request the information. I don't want to act to get this information. Platform: Windows, Subversion 1.5 and higher.

  • ASP.NET Web User Control with Javascript used multiple times on a page - How to make javascript func

    - by Jason Summers
    I think I summed up the question in the title. Here is some further elaboration... I have a web user control that is used in multiple places, sometimes more than once on a given page. The web user control has a specific set of JavaScript functions (mostly jQuery code) that are containted within *.js files and automatically inserted into page headers. However, when I want to use the control more than once on a page, the *.js files are included 'n' number of times and, rightly so, the browser gets confused as to which control it's meant to be executing which function on. What do I need to do in order to resolve this problem? I've been staring at this all day and I'm at a loss. All comments greatly appreciated. Jason

  • When is JavaScript's eval() not evil?

    - by Richard Turner
    I'm writing some JavaScript to parse user-entered functions (for spreadsheet-like functionality). Having parsed the formula I could convert it into JavaScript and run eval() on it to yield the result. However, I've always shied away from using eval() if I can avoid it because it's evil (and, rightly or wrongly, I've always thought it is even more evil in JavaScript because the code to be evaluated might be changed by the user). Obviously one has to use eval() to parse JSON (I presume that JS libraries use eval() for this somewhere, even if they run the JSON through a regex check first), but when else, other than when manipulating JSON, it is OK to use eval()?

  • Complex Django filter question

    - by HWM-Rocker
    Lets say I have this class (simplified): class Tag (...): children = models.ManyToManyField(null=True, symmetrical=False) Now I already implemented the functions get_parents, get_all_ancestors. Is there a nice pythonic way to just the top level tags? If I had designed my Tags differently (to point to the parents instead) I would just make get_all_parents().filter(children=null). My first thought is to create a new function that will go recursively through all parents and save those that has none. But is there a possibility with filters or Query-objects to do the same (with fewer lines of code)? Thanks for your help. [edit] When it is finished, it should be a hierarchical tagging system. Each tag can have children, parents, but only the children are saved. I want to get all the top level tags, that point through many children / childrens children to my tag.

  • Needing forward declaration in Ruby

    - by dbarbosa
    Hi, I am trying to write a Ruby script in one file. I would like to know if it is possible to write the "main" function in the beginning, having the other functions that are used by main, defined after it. In other words, I would like to call a not yet defined function, so that they do not depends on definition order. Just changing the order is not possible because it gives an "undefined method" error. In C/C++ we use forward declarations... is there something similar in Ruby or another solution to this?

  • Getting data from function loaded after current function

    - by Hwang
    I have 2 functions, 1 loaded before another. Some value are determine by the other function data, but since one of it has to load before the other 1, how should I get the data that is loaded after current function? private function wMessage():void { Message.width=Name.width+20; } private function wName():void { Name.x=(Message.x+Message.textWidth)-Name.textWidth; Name.y=Message.y+Message.height; } I've taken out some other unnecessary codes, but as you can see Name position is set according by the position + width of Message, but I want Message's width to be not smaller than Name

  • Why is the modal dialog in MFC actually internally modeless?

    - by pythiyam
    This question arose in my miind after reading this article: http://www.codeproject.com/Articles/3911/The-singular-non-modality-of-MFC-modal-dialogs. He mentions that the modal dialog in MFC is not strictly modal, but implemented as a modeless dialog(internally) with bells and whistles to make it behave as a modal one. Specifically, he says: The MFC command routing mechanism uses a combination of message maps and virtual functions to achieve what it does and a true modal dialog will totally wreck this mechanism because then the modal message loop is controlled outside the scope of the MFC command routing machinery Could anyone elucidate this statement? An example of what would have gone wrong if they had tried to implement a truly modal dialog would greatly clear things up.

  • Where does complexity bloat from?

    - by AareP
    Many of our design decisions are based on our gut feeling about how to avoid complexity and bloating. Some of our complexity-fears are true, we have plenty of painful experience on throwing away deprecated code. Other times we learn that some particular task isn't really that complex as we though it to be. We notice for example that upkeeping 3000 lines of code in one file isn't that difficult... or that using special purpose "dirty flags" isn't really bad OO practice... or that in some cases it's more convenient to have 50 variables in one class that have 5 different classes with shared responsibilities... One friend has even stated that adding functions to the program isn't really adding complexity to your system. So, what do you think, where does bloated complexity creep from? Is it variable count, function count, code line count, code line count per function, or something else?

  • Javascript callback on blackberry

    - by Jeff
    I'm working on a mobile project, and I have a script that is dynamically generated on the backend and then appended to the document (the html page). Desktop browsers seem to append the script correctly and call any functions in the script, however, I can't get this to happen on Blackberry phones. I know that the script is being appending because I can alert it after I append it. I just can get it to call the function in the script. For example, if I have code like this: var scriptText = document.createElement('script'); scriptText.type = 'text/javascript'; scriptText.id = 'thisScript'; scriptText.innerHTML = 'alert("hello");'; document.getElementById('idName').appendChild(scriptText); alert(document.getElementById('thisScript')); //Alerts the script element. This will alert 'hello' in desktop browsers and even the iPhone/iPodTouch, but not BlackBerry's. Anyone have any idea why? Or if there's a fix/hack?

  • Cross platform unicode path handling

    - by Matt Joiner
    I'm using boost::filesystem for cross-platform path manipulation, but this breaks down when calls need to be made down into interfaces I don't control that won't accept UTF-8. For example when using the Windows API, I need to convert to UTF-16, and then call the wide-string version of whatever function I was about to call, and then convert any output back to UTF-8. While the wpath, and other w* forms of many of the boost::filesystem functions help keep sanity, are there any suggestions for how best to handle this conversion to wide-string forms where needed, while maintaining consistency in my own code?

  • Embedded web server and gui framework for .NET applications

    - by Toad
    Hi, I'm looking for a framework which allows me to manage my application through a webbased GUI (using an embedded webserver) instead of winforms. Something like this: http://www.webtoolkit.eu/wt but then for .NET In my code I should be able to instantiate classes (like buttons, forms etc), and when a user browses to a given port, the app should render it as javascript/ajax etc etc. preferably, when buttons are pushed, a notification in my code should be called. this is a less specific question than another one I posted about extjs. I hope this will attract more viewers since it is more generic Thanks. Update: cassini like solutions don't fit the bill. Since the webbrowser is embedded in my application, there is no need for ASP.NET server side scripts. I would rather have the framework, call functions inside my application when things happen on the page. onButtonClicked() for instance.

  • Deleting SQLite rows automatically/periodically

    - by anselmophil
    Hi guys! So, i have a application that displays tasks and i created an option in the Settings menu that lets you choose in how many days all (Never, 10 days, 20 days or 30 days) these tasks should be automatically deleted. So when i open up the app there will be a method that will be called and check if theres any tasks to be deleted. I did that to challenge myself, but i'm hitting the wall with my head and i cant come up with something. So here i am in need of help! A little more information: i was trying to do something with java/android code, but from past searches i saw people dealing with it using SQL functions. Is it better? Thanks in advance guys!

  • Is there anyway to enable MultiSelect in the StyledTextCtrl

    - by John Baker
    I've noticed that the StyledTextControl (Scintilla basically) in wxWidgets has a great feature that allows multi-selections of text, just like TextMate. However wxRuby doesn't seem to have the function calls to support that feature. I'm wonder if there is a way to enable it or if there might be a way I could rewrite that wrapper to include that function. It seems strange that they would purposely omit that since they are seemingly pretty exhaustive on most functions calls. Any insight on this would be greatly appreciated. I'm trying to write an open source TextMate clone in Ruby and it's gonna be pretty hard without MultiSelect, I could probably hack something together but it'd be ugly. Thanks ahead of time.

  • Accessing structure through pointers [c]

    - by Blackbinary
    I've got a structure which holds names and ages. I've made a linked-list of these structures, using this as a pointer: aNode *rootA; in my main. Now i send **rootA to a function like so addElement(5,"Drew",**rootA); Because i need to pass rootA by reference so that I can edit it in other functions (in my actual program i have two roots, so return will not work) The problem is, in my program, i can't say access the structure members. *rootA->age = 4; for example doesnt work. Hopefully you guys can help me out. Thanks!

  • PostgreSQL - CREATE INDEX

    - by mocopera
    Hi! I'm working with PostgreSQL to create some data types written in C. For example, I have: typedef struct Point3D { char id[50]; double x; double y; double z; } Point3D; The input and output functions are working properly. But the problem is the following: Every id of Point3D must be unique (and can be NULL), so I have decided to create an unique index on this field id, but is that possible? I'm thinking in something like this: create unique index test_point3d_idx on test_point3d (( getID(columname) )); where getID returns the field ID of columname. But I need to implement getID and I am really blocked. Any advice?

  • C# Threads.Abort()

    - by Betamoo
    If a thread is running a function func1 that calls another function func2 inside it... Then I called thread.Abort() Will this stop func1 only OR func1 and func2 and all the functions func1 has called?? Thanks Edit: Here are more detail: func1 is called in a new thread, it continuously calls func2 on regular basis... func2 begin doing some work only if some array is not null.. it finishes it and return When supervisor wants to save data, it aborts Thread of func1- and then makes array null, saves data, then fill in the array with new one.. and starts Thread with func1 again.. Sometimes exception is raised because array is null in func2.. so func1 abort did not affect func2

  • JQuery never reaches success or fail on aspx returning json.

    - by David
    Basicaly I have my aspx page doing <% Response.Clear(); Response.Write("{\"Success\": \"true\" }"); Response.End(); %> My JQuery code is function DoSubmit(r) { if (r == null || r.length == 0 || formdata == null || formdata.length == 0) return; for (i = 0; i < formdata.length; i++) { var fd = formdata[i]; r[fd.Name] = fd.Value; } r["ModSeq"] = tblDef.ModSeq; jQuery.ajax({ url: "NashcoUpdate.aspx" , succsess: doRow , error: DoSubmitError , complete: DoSubmitComplete , dataType: "json" , cache: false , data: r , type: "post" }) } When I call the DoSubmit() function every thing works but the doRow or DoSubmitError functions never get called only the DoSubmitComplete function. When I look at the response text in teh DoSubmitComple function it is {"Success": "true" } Every JSON tester I have tried says that this is valied JSON. What am I doing wrong here?

  • XML RSS to HTML parser doesn't work

    - by mstr
    I'm using MCX (I don't even know if someone here is familiar with it, pretty unkown derivate of COBOL and Fortran, look it up in google when you don't believe me) Note: I'm using MCX on the MCX-WebServices server as it does neither support apache or ISS, mabye that is one problem. The thing is that I want to use the XML library to read in an XML file and convert it into an output format readable by the user. The XML lib already has all the functions I need for that, yet my program fails. #!usr/bin/mcx $PGRM.ID: index.mcx $PGRM.AT: /mstr SHOWERROR: WRITE XML.LastError --> OUTPUT DO_FLUSH xcit end\ MAIN: IMPORT Extras.XML USE Extras $XML_RSS_FILE: XML.ReadIn "rss.xml" ! $XML_RSS_FILE --> GOTO SHOWERROR $XML_RSS: XML.FormatRSS1 <-- $XML_RSS_FILE ! $XML_RSS --> GOTO SHOWERROR WRITE $XML_RSS --> OUTPUT DO_FLUSH FLUSH xcit end\ Program output: Nothing The rss.xml file 100% exists and is readable Thanks in advance

  • In MVC view page javascript file url not resolving

    - by Ashwani K
    Hello All: I have one MVC view page in which I show different links and I am using ThickBox to show a different page when ever one of these links is clicked. In these pages, I am using jQuery functions to do some changes, but I am not able to resolve the jquery file path on the view pages. I need to give absolute path something like "http://test.com/js/jquery.js". But is there any way to make it relative? I also tried getting the host url and using <%=% and <%# % but none is working. Any help? Thanks Ashwani

  • C#: Access 32-bit/64-bit DLL depending on platform

    - by Thorsten Dittmar
    Hi, we use a self-written 32bit C++ DLL from our C# applications. Now we've noticed that when the C# applications are run on a 64bit system, the 64bit runtime is automatically used and of course the 32bit DLL can not be accessed from the 64bit runtime. My question is: is there a way of using the 32bit DLL? If not, if I created a 64bit version of the DLL, would it be easily possible to let the application choose which one to P/Invoke to? I'm thinking of creating two helper classes in C#: One that imports the functions from the 32bit DLL and one that imports from the 64bit DLL, then creating a wrapper class with one function for each imported function that calls either the 32bit importer or the 64bit importer depending on the "bittyness" of the OS. Would that work? Or is there another easy way to do things?

  • C++ 'mutable' keyword

    - by Rob
    A while ago I came across some code that marked a member variable of a class with the 'mutable' keyword. As far as I can see it simply allows you to modify a variable in a 'const' method: class Foo { private: mutable bool done_; public: void doSomething() const { ...; done_ = true; } }; Is this the only use of this keyword or is there more to it than meets the eye? I have since used this technique in a class, marking a boost::mutex as mutable allowing const functions to lock it for thread-safety reasons, but, to be honest, it feels like a bit of a hack.

  • GDB skips over my code!

    - by sheepsimulator
    So, I've defined a class like DataLoggingSystemStateReceiver { DataLoggingSystemStateReceiver() { // stuff } // ... other functions here }; In main, I instantiate DataLoggingSystemStateReceiver like so: int main() { // ... run stuff Sensor sensor(port, timer); DataLoggingSystemStateReceiver dlss(); Log::notice("started"); return 0; } However, when I step through this code in gdb, it runs: Sensor sensor(port, timer); skips DataLoggingSystemStateReceiver dlss(); and continues with Log::notice("started"); What gives? EDIT: By changing DataLoggingSystemStateReceiver dlss(); to DataLoggingSystemStateReceiver dlss; in main(), the line executes. Can someone explain why?

  • Snatching the code of a Facebook fan page canvas?

    - by Andre
    I am trying to snatch the code of this fan page: http://www.facebook.com/pages/See-oho-nieps-YothG-RRofiLe/106340746065367 I need the function that suggests the fan page to the users friends automatically (not for spamming purposes as the above fan page is used for). Now by looking at the source, I know that the code is under the pagelet_tab_content, but not all of it. I have copied that part and pasted it into my own fan page. The layout looks identical but the functions does not work. Obviously something is missing. For instance, I cant find the in the source which is strange, as I know for definate that it is being used. I have been working with this all day without any result. Maybe there is someone more intelligent and experienced that could help me out?

  • How to convert an HTML table to an array in python

    - by user345660
    I have an html document, and I want to pull the tables out of this document and return them as arrays. I'm picturing 2 functions, one that finds all the html tables in a document, and a second one that turns html tables into 2-dimensional arrays. Something like this: htmltables = get_tables(htmldocument) for table in htmltables: array=make_array(table) There's 2 catches: 1. The number tables varies day to day 2. The tables have all kinds of weird extra formatting, like bold and blink tags, randomly thrown in. Thanks!
